Description

  The present invention relates to an elevator control device that controls a plurality of elevators that are controlled in group management operation, and more particularly to an elevator control device that is suitable for restoring an elevator that has been stopped due to an earthquake shake.

  Conventionally, a plurality of elevators that are controlled in group management operation have been equipped with an elevator control device that checks the abnormality of each elevator when an earthquake occurs and restores or performs appropriate processing based on the presence or absence of the abnormality. ing. This elevator control device operates in seismic control when there is more than a predetermined vibration at the time of the earthquake, and the earthquake restoration diagnosis operation that determines the necessity of restoration of the elevator stopped by this seismic control operation via the monitoring device Operation control is performed.

  When the elevator controlled in this way is subjected to earthquake shaking, seismic control operation is performed and each elevator stops. After each elevator is stopped, an earthquake recovery diagnosis operation is performed, and these stopped elevator cars are run to check whether there is an abnormality and perform a recovery diagnosis. When no abnormality is detected in the elevator, the elevator is automatically restored. When an abnormality is detected in the elevator, the elevator maintenance company is notified and appropriate processing is performed.

  However, when diagnosing the restoration of the elevator described above, if a plurality of elevator cars are run and simultaneously run in a diagnostic operation to check whether there is an abnormality, the elevators are affected by the running of the diagnostic operation of each elevator. There was a problem that anomalies were detected incorrectly. Therefore, there is known an elevator control device that prevents erroneous detection of this type of abnormality by determining the start order of a plurality of elevators and sequentially performing diagnostic operation (see, for example, Patent Document 1).

JP 2008-7237 A

  Here, between the elevator car and the control panel, a plurality of communication cables, power cables and the like are formed as a single moving cable. For this reason, when the elevator is subjected to an earthquake shake, the moving cable may be caught by equipment installed in the hoistway. In this case, when the elevator whose operation is controlled by the elevator control device disclosed in Patent Document 1 described above is subjected to the earthquake recovery diagnosis operation, the result is that all the elevators run and perform the diagnosis operation. And the apparatus in the hoistway hooked by this moving cable, ie, an elevator apparatus, is damaged, and there exists a problem which an elevator breaks down. Thereby, there exists a possibility that the serviceability of the elevator user after an earthquake occurrence may fall remarkably. In particular, if the number of elevators is small and the elevator breaks down, it takes time until the elevator is restored, and the elevator cannot be used during this time, which is inconvenient.

  The present invention has been made based on the actual situation of the prior art as described above. The purpose of the present invention is to provide an elevator that can perform an earthquake recovery diagnosis operation to an elevator that has a low risk after an accident and has the highest possibility of recovery. It is to provide a control device.

In order to achieve the above object, the elevator control apparatus according to the present invention causes each of a plurality of elevators to be controlled in group management operation to perform seismic control operation when there is a predetermined swing or more when an earthquake occurs. Records the operating status of the multiple elevators when an earthquake occurs in an elevator control device that performs operation control to make an earthquake recovery diagnosis operation to determine whether restoration is necessary for an elevator that has been suspended due to earthquake control operation Operating status recording means, and priority order determining means for determining which one specific elevator to perform the earthquake recovery diagnosis operation from the operating status of each of the plurality of elevators recorded by the operating status recording means, A diagnostic operation indicator that outputs a command to execute the earthquake restoration diagnosis operation of the specific elevator determined by the priority determination unit And means, the operating status to be recorded in the operational status recording device checks the running status to ensure the elevator during the earthquake or stopped or running, the position of the car of the elevator in the event of an earthquake The priority order determining means determines that the elevator is the specific elevator when only one elevator is recorded as being stopped by the operating status recording means, and the operating status recording means When a plurality of elevators are recorded as being stopped, the elevator closest to the lowest floor among the plurality of elevators is determined as the specific elevator, and all the elevators are traveling by the operating status recording means Is recorded, the elevator closest to the lowest floor is determined as the specific elevator .

  The elevator control apparatus configured as described above is the operation status of each elevator recorded in the operation status recording means among the stopped elevators when the elevator is subjected to earthquake control operation and stopped due to the earthquake. From the moving cable caught by the shaking of the earthquake and the equipment in the hoistway hooked by this moving cable, that is, the elevator that has the lowest possibility of damaging the elevator equipment is specified by the priority determination means, and the diagnostic operation command means The earthquake restoration diagnosis operation can be carried out preferentially from the specified specific elevator specified by the command.

For this reason, even if it is expected that the moving cable will be caught by equipment installed in the hoistway due to the shaking of the earthquake, these elevator equipments are likely to be damaged. It can be determined whether to restore the elevator. In this way, it is possible to cause the elevator having a low risk after the occurrence of the accident and having the highest possibility of recovery to perform the earthquake recovery diagnosis operation, and it is possible to prevent the elevator equipment from being damaged. Further, according to the present invention, it is possible to determine the specific elevator by the priority order determination means based on the traveling condition and position situation of each elevator recorded in the operating condition recording means, and to make the earthquake restoration diagnosis operation preferentially performed. It does not require complicated setting work and is easy to use. Furthermore, according to the present invention, the priority determining unit can easily determine the elevator with the lowest possibility of damaging the elevator equipment by using the traveling condition as the highest priority determination criterion rather than the position condition. Then, since the priority order judging means uses the position situation as the judgment criterion next to the running situation, it is possible to make a decision to reliably determine one specific elevator, so that the stability of the apparatus can be prevented without causing a malfunction. Can be improved.

  The elevator control device according to the present invention is characterized in that, in the above invention, the monitoring device includes the operation status recording means, the priority order determination means, and the diagnostic operation command means. If comprised in this way, since these three means of an operation condition recording means, a priority order determination means, and a diagnostic operation command means can be put together in one device, it can accommodate compactly.

  In the elevator control device of the present invention, when an earthquake occurs and a predetermined or greater earthquake is shaken, the earthquake control operation is performed and each elevator is stopped. Then, from the operating status of each elevator recorded in the operating status recording means, the priority determining means sets the elevator that has the lowest possibility of damaging elevator equipment such as moving cables among these elevators to one specific elevator. Make a decision to decide. When the specific elevator is determined, the diagnostic operation command means outputs a command to execute the earthquake restoration diagnosis operation of the specific elevator, and the earthquake restoration diagnosis operation of the specific elevator is performed.

  Therefore, even if it is expected that the moving cable will be caught by equipment installed in the hoistway due to the shaking of the earthquake, the earthquake restoration diagnosis operation should be given priority to the specific elevator that is least likely to damage the elevator equipment. Therefore, it is possible to secure an elevator to be restored and to determine whether or not to restore an elevator that is likely to be damaged by the elevator equipment before the earthquake restoration diagnosis operation is performed. As a result, the earthquake recovery diagnosis operation can be performed on the specific elevator having the lowest risk after the occurrence of the accident and the highest possibility of recovery, and it is possible to suppress the damage of the elevator equipment caused by the specific elevator.

  Therefore, the specific elevator can be returned to normal operation, and the serviceability of the elevator user after the occurrence of the earthquake can be improved.

I have.

  The control panels 3 and 13 of these elevators 1A and 11A are connected to the group management panel 20, and the elevators 1A and 11A are group-controlled. The control panels 3 and 13 are connected to monitoring devices 4 and 14 for monitoring the status of the elevators 1A and 11A and inputting / outputting commands such as earthquake restoration diagnosis operation. Are connected to each other and transmit / receive information of the elevators 1A and 11A, respectively.

  The monitoring device 4 includes an input / output device 4D that transmits and receives commands and various information from the control panel 3 and the like, and operating status recording means that records the operating status of the two elevators 1A and 11A when an earthquake occurs, for example, A RAM 4C and a ROM 4B, and a processing device 4A that performs appropriate processing based on information received from the input / output device 4D, the RAM 4C, and the ROM 4B are provided.

  Further, the processing device 4A includes priority order determination means for performing determination to determine one specific elevator to be operated for earthquake recovery diagnosis from the operating status of each of the two elevators 1A and 11A recorded in the RAM 4C and the ROM 4B.

  Similarly, the monitoring device 14 includes an input / output device 14D that transmits and receives commands and various information from the control panel 13 and the like, and an operation status recording unit that records the operation status of the two elevators 1A and 11A when an earthquake occurs. For example, it includes a RAM 14C and a ROM 14B, and a processing device 14A that performs appropriate processing based on information received from the input / output device 14D, the RAM 14C, and the ROM 14B.

  Here, the operation state includes a traveling state for confirming whether the elevators 1A and 11A are traveling or stopped when the earthquake occurs, and a positional state for confirming the positions of the cars 1B and 11B of the elevators 1A and 11A when the earthquake occurs. It is out.

  Hereinafter, the operation when the elevators 1A and 11A whose operation is controlled according to the embodiment of the present invention is subjected to an earthquake shake of a predetermined level or more will be described with reference to FIGS.

  As shown in FIG. 2, when an earthquake occurs and the elevators 1 </ b> A and 11 </ b> A are shaken more than a predetermined value (S <b> 100), the earthquake detector 10 outputs earthquake information to the control panels 3 and 13. Upon receiving this earthquake information, the control panels 3 and 13 stop the cars 1B and 11B on the nearest floor, and close the doors 2 and 12 after the passengers in the cars 1B and 11B get off.

  The operating status of the elevators 1A and 11A at the time of the earthquake is transmitted to the monitoring devices 4 and 14 via the control panels 3 and 13, respectively, and stored in the RAMs 4C and 14C (S101).

  Next, the monitoring device 14 of the elevator 11A transmits the operating status of the elevator 11A stored in the RAM 14C to the monitoring device 4 and stores it in the RAM 4C (S102).

  Next, after a lapse of a certain time (S103), the processing device 4A of the monitoring device 4 determines from the operating status of the elevators 1A and 11A stored in the RAM 4C to determine one specific elevator for earthquake recovery diagnosis operation, and diagnoses it. This specific elevator is caused to perform earthquake restoration diagnosis operation by the operation command means (S104).

  At this time, as shown in FIG. 3, the priority order determination means determines whether the traveling state of the two elevators 1A and 11A stored in the RAM 4C and the ROM 4B is stopped or traveling (S200).

  If at least one of the two elevators 1A and 11A is in a stopped state, the priority determination means is only one of the two elevators 1A and 11A that has a stopped traveling state. It is determined whether or not (S201).

  When only one elevator is stopped in the traveling state of the two elevators 1A and 11A, the stopped elevator is determined as a specific elevator (S203), and the processing device 4A uses the diagnostic operation command means to specify this Elevator earthquake recovery diagnosis operation is carried out (S204).

  On the other hand, when the traveling conditions of the two elevators 1A and 11A are both traveling in S200 and when the traveling conditions of the two elevators 1A and 11A are both stopped in S201, of these elevators 1A and 11A The elevator closest to the lowest floor is determined as the specific elevator (S202), and the processing device 4A causes the specific elevator to perform the earthquake restoration diagnosis operation by the diagnosis operation command means (S204).

  When the specific elevator, for example, the elevator 1A is determined as the specific elevator in this way and the earthquake restoration diagnosis operation of the elevator 1A is performed, as shown in FIG. 2, the presence or absence of an abnormality in the elevator 1A is confirmed (S105).

  When it is confirmed that there is an abnormality in the elevator 1A, the elevator 1A is stopped and not restored, and the elevator 11A is terminated without performing the earthquake restoration diagnosis operation (S106). On the other hand, when it is confirmed that there is no abnormality in the elevator 1A, the elevator 1A is restored to normal operation (S107).

  In addition, when there is a floor that can be serviced only by unrecovered units other than the elevator 1A, it is processed in the following processing procedure. For example, when there is a floor that can be serviced only by the elevator 11A, the earthquake recovery diagnosis operation of the elevator 11A is performed (S109), and whether or not there is an abnormality in the elevator 11A is confirmed (S110).

  When it is confirmed that there is an abnormality in the elevator 11A, the elevator 11A is stopped and terminated without being restored (S106). On the other hand, when it is confirmed that there is no abnormality in the elevator 11A, the elevator 11A is restored to normal operation (S111).

  According to the embodiment of the present invention configured as described above, when the elevators 1A and 11A are subjected to earthquake vibrations of a predetermined level or more in S100, and the earthquake control operation is performed and stopped, each recorded in the RAM 4C and the ROM 4B is recorded. From the operating status of the elevators 1A and 11A, according to the processing procedure shown in FIG. 3, the priority determination means of the monitoring device 4 determines whether or not the traveling status is stopped rather than the position status in S200 and S201. By setting the position status as the second determination criterion in S202, it is possible to easily determine the elevator 1A that is least likely to damage the elevator equipment as a specific elevator without causing malfunction.

  Then, when the processing device 4A outputs the command of the diagnostic operation command means and preferentially executes the earthquake restoration diagnosis operation means from the elevator 1A, it is confirmed in S105 that there is no abnormality in the elevator 1A. Since the elevator 1A can be quickly restored to normal operation, the serviceability of the elevator user after the occurrence of the earthquake can be improved.

  Furthermore, when it is confirmed in S105 that there is an abnormality in the elevator 1A, the normal operation of the elevators 1A and 11A is stopped in S106. That is, the elevator 11A is finished without being restored before the earthquake restoration diagnosis operation of the elevator 11A having a higher possibility of damaging the elevator equipment than the elevator 1A. Thereby, it is possible to prevent the elevator devices from being damaged by the normal operation of the elevators 1A and 11A or the earthquake recovery diagnosis operation of the elevator 11A.

  In this way, the earthquake recovery diagnosis operation can be performed on the elevator 1A having a low risk after the occurrence of an accident and the highest possibility of recovery, and it is possible to prevent the elevator equipment from being damaged.

  Further, in the embodiment of the present invention, the monitoring device 4 has a compact configuration including, for example, three means of a RAM 4C and a ROM 4B for recording the operating status of the elevator 1A, a priority order judging means, and a diagnostic operation command means. Can do. Moreover, although the monitoring apparatus 14 is provided with RAM14C and ROM14B which record the operating condition of the elevator 11A, for example, it can be set as the simple structure which does not include a priority order determination means and a diagnostic operation command means.

  Further, in the embodiment of the present invention, as described above, the processing device 4A of the monitoring device 4 can determine the specific elevator only by the traveling state and the position state of the elevators 1A and 11A by the priority order determination unit. It is easy to use without requiring any setting work.
